Here is the list of Si-based image sensor companies, as of June 2010. These are only silicon-based vendors, no exotic materials here. The companies are sorted according to the market they are pursuing. Not all the companies from Mainstream High Volume section are really that high volume. Rather, they are operating at high volume market with different degrees of success. Please email me in case of errors.

The info about other companies is unofficial. For instance, Newport Media is most probably closed in 2008 or so, but no official announcement has been made. CmoX maintained its web site for many years after the company has been dissolved.

Mikro-Tasarim is a relatively new company that develops ROICs and imaging sensors since 2008 (www.mikro-tasarim.com.tr). Two of its products are MT6425CA (640x512-25um CTIA ROIC) and MT6415CA (640x512-15um CTIA ROIC).

Hello Vladimir,Here is a link to the Korean Semiconductor industry Association. Maybe I missed a link on the blog but just in case you missed it. This is a good source to track down some companies. Hope you are doing well. http://www.ksia.or.kr/renewal/eng/#

Thank you, Dave. I like your syntax for the acquisitions. May be it makes sense to arrange the list that way. The problem is what to do with the defunct companies, such as Altasens-JVC-Kenwood. In the past, I just deleted such companies from the list.

hi Vlad, as always thanks for your efforts. Since this may be the only public, historical record of image sensor companies, it would be great if you can keep even the dead ones on the list. It is kind of a genealogy project.

I'd keep everyone in the list, otherwise readers will just wonder why some company they remember is missing. Also, if you want to use the syntax, you may also want to put the transaction dates with the arrows like e2V <[2014] Anafocus. Maybe Dead ones could just be labeled like [d2016] after their names. it would probably also be useful to trace back to university or government origins so you might have: ON Semi < Aptina < Micron < Photobit < JPLI think it would be fun to make a chart for image sensors like this one for rock music - http://www.fakeplasticrock.com/wp-content/uploads/genealogy-of-pop-and-rock-music.png - but I am still too busy to do it. It would have to go back at least to bucket-brigade memory and popping the tops off DRAM. I don't know who made the first photodiode array.
